** Make CapsLock another Control

- add =ctrl:nocaps= in =/etc/default/keyboard=
- run =udevadm trigger --subsystem-match=input --action=change=
- run =setupcon= in a TTY

** apt install (1/n)
git greybird-gtk-theme elementary-xfce-icon-theme emacs

git suggests git-doc: why of course, good idea!

emacs suggests emacs-common-non-dfsg: right, what was that again?
Documentation, IIRC?  What does APT have to say?

#+BEGIN_EXAMPLE
$ apt show emacs-common-non-dfsg
Package: emacs-common-non-dfsg
State: not a real package (virtual)
N: Can't select candidate version from package emacs-common-non-dfsg as it has no candidate
N: Can't select versions from package 'emacs-common-non-dfsg' as it is purely virtual
N: No packages found
#+END_EXAMPLE

… What does https://packages.debian.org/emacs-common-non-dfsg say?

** Clone dotfiles
Generate SSH keys and add them to GitLab through the web UI.  "Clone"
(init, add remote, fetch, reset) dotfiles.

** Tweak dotfiles
Set EMAIL in .profile; copy .profile to .xsessionrc (AFAICT XFCE does
not read ~/.config/environment.d) to get PATHs.

In .bashrc, enable globstar and autocd, uncomment grep and ls aliases,
source personal .bash_prompt.

Fun fact!  git can guess user.email from $EMAIL and user.name from the
[[https://en.wikipedia.org/wiki/Gecos_field][GECOS field]].
